A device for fixing step-by-step ascending and descending ladders during shipbuilding

Abstract

The invention discloses a device for fixing a subsection rising-and-falling ladder in a shipbuilding process, which comprises a hook plate for fixing a ladder; a hook shape with an opening is arranged at one end of the hook plate; a clamp plate and an embedded nut are arranged on the hook plate; one end of the clamp plate is fixed on the hook plate; the other end of the clamp plate bends, is in parallel to the hook plate and is positioned above the embedded nut; and a screw which is used for coordinately clamping a panel is installed in the embedded nut. The device provided by the invention is suitable for fixing the rising-and-falling ladder in the shipbuilding process, ensures that the rising-and-falling ladder is fixed and has no movement and can provide a safe and fast construction site for building a ship; and the device provided by the invention can avoid the phenomenon that the rising-and-falling ladder is arranged on subsection of a ship in a point welding way in the prior art, and trace left on the panel and damage on the ladder can be found when the device is dismantled; and in addition, the device is convenient to dismantle and the repair workload of the panel and the ladder can reduced.

Description

technical field [0001] The invention relates to a device for securing a ladder. Background technique [0002] With the continuous development of the shipbuilding industry, various new technologies and new equipment are continuously introduced into the shipbuilding process, which makes the speed of shipbuilding faster and faster. How to ensure safety at a faster pace of production is more and more valued by people. It is understood that in the past ship production process, due to the low safety level of the ladders on the ship's sections, the on-site ladders slipped and caused injuries, and the shipowner and ship inspection refused inspection due to the unsafe stages of getting on and off the ship. Occurs from time to time; and in the general grouping stage of ship sections, a large number of ship sections are assembled on the ground, and the ladders of ship sections must be spot welded firmly before construction can be carried out. After spot welding, the ladders are inconve...

Problems solved by technology

It is understood that in the past ship production process, due to the low safety level of the ladders on the ship's sections, the on-site ladders slipped and caused injuries, and the shipowner and ship inspection refused inspection due to the unsafe stages of getting on and off the ship. Occurs from time to time; and in the general grouping stage of ship sections, a large number of ship sections are assembled on the ground, and the ladders of ship sections must be spot welded firmly before construction can be carried out. After spot welding, the ladders are inconvenient to move, and the Solder feet left on the segment need to be dealt with
